        public float getWidthFromFont​(int code)
                               throws java.io.IOException
        Description copied from interface: PDFontLike
        Returns the width of a glyph in the embedded font file.
        Parameters:
        code - character code
        Returns:
        width in glyph space

        java.io.IOException - if the font could not be read
      • isEmbedded

        public boolean isEmbedded()
        Description copied from interface: PDFontLike
        Returns true if the font file is embedded in the PDF.
      • getHeight

        public float getHeight​(int code)
                        throws java.io.IOException
        Description copied from interface: PDFontLike
        Returns the height of the given character, in glyph space. This can be expensive to calculate. Results are only approximate.

        Warning: This method is deprecated in PDFBox 2.0 because there is no meaningful value which it can return. The PDFontLike.getWidth(int) method returns the advance width of a glyph, but there is no corresponding advance height. The logical height of a character is the same for every character in a font, so if you want that, retrieve the font bbox's height. Otherwise if you want the visual bounds of the glyph then call getPath(..) on the appropriate PDFont subclass to retrieve the glyph outline as a GeneralPath. See the cyan rectangles in the DrawPrintTextLocations.java example to see this in action.

        Parameters:
        code - character code
        Throws:
        java.io.IOException
      • encode

        protected byte[] encode​(int unicode)
                         throws java.io.IOException
        Description copied from class: PDFont
        Encodes the given Unicode code point for use in a PDF content stream. Content streams use a multi-byte encoding with 1 to 4 bytes.

        This method is called when embedding text in PDFs and when filling in fields.

        Specified by:
        encode in class PDFont
        Parameters:
        unicode - Unicode code point.
        Returns:
        Array of 1 to 4 PDF content stream bytes.
        Throws:
        java.io.IOException - If the text could not be encoded.
      • getStringWidth
